Eve Security, a company focused on runtime security for AI agents, has raised $4.5 million in new funding.
The extended seed round was led by Run Ventures, with participation from Dreamit Ventures and Blu Ventures, along with continued investment from LiveOak Ventures. The funding brings Eve Security’s total funding to $7.5 million.
Eve Security helps businesses monitor and control AI agents while they work with sensitive data, applications and company infrastructure.
“Agents are becoming extraordinarily capable, and enterprises are giving them access to increasingly valuable systems. The OpenAI incident showed what can happen when an agent’s pursuit of an objective takes it somewhere its creators never intended,” said Nadav Cornberg, co-founder and CEO at Eve Security. “You cannot secure that world simply by deciding in advance what an agent should and shouldn’t do. You have to understand what it is doing, why it is doing it and have the ability to intervene while it is happening.”
The company’s platform provides real-time visibility into AI agent activity and can detect unusual or high-risk actions. It can also intervene before an AI agent carries out an action that could affect a critical system.
Eve says traditional cybersecurity tools are not designed to fully understand the behavior of autonomous AI agents. Its platform is designed specifically to monitor the actions of AI agents and enforce security policies during runtime.
The company has introduced features including session tainting, which can adjust restrictions based on an agent’s access to sensitive data and previous actions.
“AI runtime security is developing into a significant new security category, and we believe there will be multiple important companies built in this market,” said PT Ungvichian, Run Ventures. “Eve recognized early that securing autonomous systems requires understanding and controlling behavior at runtime, and the company is exceptionally well positioned to capitalize on that shift.”
“We had high conviction in the technical thesis. What we wanted next was market proof,” said Cornberg. “We’re now seeing that pull directly from CISOs and customers. This round lets us put significantly more resources behind turning that early demand into a repeatable business.”
Eve also supports AI and data platforms including Databricks, Glean, Microsoft Copilot Studio, Amazon AgentCore and Amazon Bedrock. Its platform can turn security policies into automated enforcement rules, with more than 85% of policy-matched requests evaluated and enforced deterministically, according to the company.
Eve began its go-to-market efforts in January and said enterprise customers are expanding their use of its platform.
The company will use the new funding to expand its go-to-market operations and grow revenue. Over the next 12 to 18 months, Eve plans to demonstrate its runtime AI security approach across multiple enterprise customers.
Eve Security was founded to help companies deploy autonomous AI agents while maintaining security, governance and accountability.
